I gave the pledge of allegiance to Messenger of Allah ﷺ for to offer prayers perfectly, to pay Zakat regularly, and to give good advice to every Muslim.  

البخاري:٥٢٤حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى قَالَ حَدَّثَنَا يَحْيَى قَالَ حَدَّثَنَا إِسْمَاعِيلُ قَالَ حَدَّثَنَا قَيْسٌ عَنْ جَرِيرِ بْنِ عَبْدِ اللَّهِ قَالَ

بَايَعْتُ رَسُولَ اللَّهِ ﷺ عَلَى إِقَامِ الصَّلاَةِ وَإِيتَاءِ الزَّكَاةِ وَالنُّصْحِ لِكُلِّ مُسْلِمٍ
